EDiVARD M. HEYLMAN, OF ROCKFORD, ILLINOIS, ASSIGNOR TO THE ROCK- FORD MANUFACTURING COMPANY.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent N 0. 451,871, dated May 5, 1891.

Application filed July 31, 1890.

To all whom, it may concern.-

Be it known that I, EDWARD M. IIEYLMAN, a citizen of the United States, residing at Rockford, in the county of YVinnebago and State of Illinois, have invented certain new and useful Improvements in Corn-Planting Machines, of which the following is a specification.

The object of this invention is to form a connection between a foot or hand lever and the marker, so that the same movement of the hand or foot lever which raises the runners from the ground will also raise the marker.

The further object of this invention is to form a universal-joint connection between the carrying-frame and runner-frame for the purpose of permitting a rising and falling movement and an oscillatory movement to the runner-frame and an adjustable device for limiting the oscillatory movement.

The further object of this invention is to provide means for regulating the running depth of the runner-frame, the connection being such as to permit a limited rising movement to the runner-frame, and a foot-lever by means of which the runner-frame maybe held in contact with the ground.

The further object of this invention is to extend the axle of the carrying-wheels beyond one of the carrying-wheels and locate thereon a reel for holding the check-wire, said reel having a friction engagement with the axle to regulate its holding force.

The further object of this invention is to provide a check-valve, which is located in the heel end of the runner, said valve pivoted to move in the lengthwise direction of the runner and having its lower end vertically adj ustable, and means for imparting the required movement to the valve.

The further object of this invention is to impart an intermittent rotary movement to a horizontal seed-wheel by means of a rocking yoke, so that in the forward reciprocating movement of the yoke one of its arms will push the seed-wheel sufficiently to allow a deposit of the corn, and in its backward reciprocating movement the other arm of the yoke will engage the seed-wheel on the opposite Serial No. 360,529. (No model.)

side, revolving it sutficiently to permit the deposit of the corn located in the next cell.

The further object of this invention is an attachment on the under side of the corn-cutoff device, which will insure the deposit of the proper number of kernels, and in the various combinations of the above-described elements. x

In the accompanying drawings, Figure 1 is an isometricaLrepresentation of a corn-plant 6o ing machine embodying some of my improvements.

Fig. 9 is an isometrical representation of the seed-wheel and the yoke for imparting an intermittent rotary movement to the wheel. Fig. 10 is a vertical central section through the seed cut-oft, showing the location of my attachment to the same. Figs. 11, 12, 13, and 14 are views of my improved check-wire button.

The main frame of my machine consists of an axle 1, carrying supporting-wheels 2, and a suitable framework composed of longitudio nal bars 3, which are secured upon the axle about midway of theirlength. The rear ends of these bars are held separated by a cross-bar 4. A drivers seat is located upon the bars 5, which are held in their proper position relatively with the main frame by braces 6, secured to the cross-bar 4. The forward ends of the seat-supporting bars have a connection with toothed segment 7, clamped to the axle between the longitudinal bars of the main I00 frame. Alever S has a pivotal connection between the toothed segments, and is provided with the usual thumbdever connection with the segments. To this lever above its pivotal connection is secured a lengthwise bar having a rear portion 9 and a forward portion 10. The rear portion 9 is provided with a foot-rest 11. A cord '12 is connected to this rearward portion and passes over a sheave l3, suspended from the seat-supporting bars. The free end of this cord is connected to a marker 14, which has a pivotal connection with the main supporting-frame, and a cord 15 connects the marker with the main frame.

Near the end of the forward portion 10 is pivoted a socket 16, which is provided with a foot-rest 17, rising therefrom. The free end of this socket has a connection with the runner-frame through the medium of links 18 and 19, said links having a pivotal connection with each other, the one having a pivotal c011- nection with the socket and the other having a pivotal connection with the rear extension of the runner-frame. The main carryingframe has a universal-joint connection with the runner-frame by means of a three-armed coupling, consisting of a transverse portion 20, which has a pivotal connection at its ends with the forward ends of the longitudinal bars 3 of the main frame. The lengthwise arm 21 of this coupling hasa pivotal connection at its forward end with the tongue, and its rear end has a pivotal connection through the medium of a bracket to the transverse bar 23 of the runner-frame. To the rear face of the bar 23 are secured vertically-slotted brackets 24:, which are located beneath the transverse portion of the universal coupling.

By formingaconnection between themarker and the combined hand and foot lever, as I move the hand-lever rearward, and consequently the foot-lever downward, for the purpose of raising the runner-frame out of the ground, I also raise the marker free from the ground,which is especially useful in turning corners or in transferring the machine to and from the field, and as soon as the runnerframe is lowered the marker will also be in proper position to do the work. lVhen the runner-frame has been lowered to its working position, the hand-lever connection with the two segments willprevent the further descent of the runners into the ground; but by the employment of the socket 16, which has a pivotal connection with the forward portion 10 and by reason of its pivotal connection with the runner-frame, the runnerframe will be free to rise until the lower edge of the portion 10 comes in contact with the under side of the socket, thereby preventing further ascent of the runner-frame. This movement willpermit the runner-frame to pass over slight obstructions withoutinterfering with the main supporting-frame, and the driver seated in his seat, by placing his feet on the foot-rest of this socket, can force the runners into the ground when it may be deemed necessary. By the universal-joint connection between the main supporting-frame and the runner-frame the runner-frame is free to follow theirregularities of the ground without interfering with the main supporting-frame. It may be deemed necessary under certainconditions to limit the extent of this oscillatory movement of the runner-frame. Therefore I employ the slotted brackets 24, by means of which I am able to give the runner-frame the required oscillatory movement, and when deemed necessary can bring both brackets up against the under side of the transverse portion of the coupling, thereby forming a rigid connection between the main frame and runner-frame, so far as any oscillatory movement is concerned.

' By extending the axle of the supportingwheels I am able to locate thereon a reel for the purpose of holding the check-wire. This reel consists of a hub 25, provided with a flange 26, from which radiate arms 27, upon which the wire is wound. The outer portion of the hub 25 is reduced in size, upon which is placed a two-part clamp 28, having a pivotal connection with each other, the other ends of the clamp having a screw-bolt 29 passed therethrough, a spring 30 placed thereon, and a thumb-nut connection therewith, by means of which the clamp may be held in its connection with the reduced portion of the yoke. Upon the extreme outer end of the axle is secured a clamp 31, from the inner face of which projects a stud 32, which forms the pivot for the two parts of the clamps surrounding the hub. As the clamp 31 is firmly held in its connection with the axle, the twopart clamp is also held in the same position; but the reel is free to rotate on the axle until the pressure applied by the thumb-nut and spring to the two-part clamp around thehnb of the reel be increased to such an extent as to prevent the reel from turning. This friction may be increased or diminished as becomes necessary in winding or unwinding the check-wire from the reel. The runner 33 has its rear side open, and its lower rear end is curved outward, as shown at 34:, Fig. 1, so as to raise the ground on each side of the runner at the point Where the corn is deposited, which will close in after the runner has passed, leaving the corn evenly covered. The rear face of the runner is closed by a valve 35, which has a pivotal connection with the runner at 36. An extension 37 is adjustably secured to the lower end of the valve by a bolt and thumb-nut 38 and a series of holes in the extension. The lower end of the extension is curved and rests against the vertical face 39 of the runner. The mechanism for imparting the required movement to this valve consists of a cam-slide 40, which is operated upon either by hand or selfchecker and is caused to reciprocate. This cam-slide is held beneath the bottom 41 of the seed-box in guideways 42 and is of channeliron form, and a cam 43 is located within its grooved under face.

The upper end of the check-valve is provided with a roller 44, so located as to be moved by the cam-slide in its reciprocation, which will cause the check-valve to oscillate on its pivotal connection with the runner.

IVhen the canrslide is at one end of its movement, the parts will occupy the position shown at Fig. 4, which will allow the corn to drop and be held by the curved lower end of the extension. In the movement of the cam slide to the other end of its stroke the cam will engage the roller 44 on the upper end of the check-valve, thereby moving the valve until it engages the offset 45, which will receive the corn discharged by the seed-disk. This movement will also move the lower end of the check-valve from engagement with the vertical face 39 of the runner, thereby allowing the deposit of the corn held by the extension. The return of the cam-slide will move the check-valve to its original position, which will close its lower end and allow the corn held by the offset to drop. The return movement of the check-valve is accomplished by a spring 46, having a connection therewith and with a stationary support.

I have placed an extension on the lower end of the check-valve for the purpose of ad mitting of a vertical adjustment of its lower end, which I find necessary in wet weather; but in dry weather I am able to discharge the corn in close contact wit-h the ground, thereby preventing the kernels from scattering.

My seed-dropping device is of the rotary form and consists of a disk 47, having seedcells 48 therein. This disk rotates around a central stud 49, rising from the bottom 41 of the seed-box.

From the periphery of the seed-disk radiate projections or teeth 50. The bottom of the seed-box is slotted, and an arm 5], rising from the upper face of the cam-slide, moves in said slot and has its upper end in fork form.

A yoke 52 is fitted with a reduced portion 53, which fits between the forks of the arm 51 and is held from lengthwise movement by the arms of the yoke and an enlarged end 54. One arm of the yoke has a downturned end 55, while the other arm is provided with a hook. As the cam-slide 40 reciprocates, it carries the yoke with it. As the cam-slide moves outward, the end 55 of one of the yoke-arms will engage one of the projections 50 and cause the said disk to rotate until the following seed-cell comes over the opening 56 in the bottom of the seed-box, said opening being over the opening in the runner between the runner-back and check-valve, and when it has completed its movement the stud 57, rising from the cam-slide, will engage the end of one of the projections 50, thereby forming a lock against forward movement. In the return movement of the cam-slide the hooked end of one of the yoke-arms will reach over and engagea projection 50 and turn the seed 7o disk until the next cell is over the dischargeopening, when the stud 58 will engage one of the projections 50 and form a look. This intermittent rotary movement is repeated at each reciprocation of the cam-slide and yoke.

By the use of a yoke of the construction herein shown, which has a rocking engagement with the cam-slide, the free ends of'the arms will always be sure to engage the projections on the seed-disk, as it only has three points of contact. Consequently one arm can pass over a projection without interfering with the action of the other arm.

My improved cut-off is located over the seed-discharge opening through the bottom of the seed-box, and consists of a latch 59, pivoted midway of its length. A spring 60 holds the outer end of the latch down in a yielding manner, and a cap 61 holds the latch in position. To the under side of the cut-oif I have riveted a flat spring-plate 62 in such position that the space between the depend:

ing ends of the cut-off and spring-plate will embrace the discharge-opening. In the use of a spring cut-off it is found that should a kernel of corn project above the surface of the seed-disk the depending end of the cutoff will rise, thereby allowing the kernel to I pass under; but in passing under it will be snapped out of the seed-cell by the spring action of the cut-off and will not be discharged with the remaining kernels in the cell. By the employment of my spring attachment the kernels will fly against it and the spring-plate will force the kernel into its cell and be discharged with the other kernels.

At Figs. 11, 12, 18, and 14 I have shown an improved construction of check-wire button, which is of spherical form, having a central opening 63. This opening has one end 64 contracted. The opposite end is formed with lips 65.

In building up a number of links of chain embodying my improved button one end of the wire 66 is headed and passed through the opening in the button. The headed end of another sect-ion of wire is placed within the opening of the button, so that the heads of two sections will be together. The lips 65 are then compressed around the wire, which will form a connection between two sections of wire, 'and space enough is left between the heads within the button to allow the untwisting of the wire. Any number of sections of wire may be thus joined.

I claim as my invention'- 1.
